Abstract

Декодер декодирует первый набор данных и использует первый набор декодированных данных для восстановления сигнала в соответствии с первым уровнем качества. Декодер дополнительно декодирует второй набор данных и идентифицирует операцию повышающей дискретизации, заданную вторым набором декодированных данных. Декодер применяет операцию повышающей дискретизации, идентифицированную во втором наборе декодированных данных, к восстановленному сигналу на первом уровне качества, чтобы восстановить сигнал на втором, более высоком уровне качества. Чтобы улучшить восстановленный сигнал, декодер извлекает остаточные данные из второго набора декодированных данных. Остаточные данные указывают, как изменить восстановленный сигнал на втором уровне качества после применения операции повышающей дискретизации, которая описана выше. Декодер затем изменяет восстановленный сигнал на втором уровне качества, как задано остаточными данными.
